About iShares S&P Mid-Cap 400 Growth ETF

How the fund works
The fund passively tracks the S&P MidCap 400 Growth Index without leverage. It weights holdings by float-adjusted market value and uses representative sampling, so it may not own every stock in the index exactly. The index is rebalanced periodically. The expense ratio is about 0.16% a year, and the fund pays dividends quarterly, with a yield of roughly 0.6%. Industrials are the largest sector at about 28% of the portfolio. Mid-cap growth stocks tend to swing more than large caps: its three-year beta is about 1.06 and volatility about 18-19%.
